What is happening is that you are calling a pick on the object before C2 has hit a top level event. Where as before R110 the function would have run inside the scope of the object creation and been considered a sub-event, a bug fix (as I just found out myself) in R110 means the functions need to repick the object they are working with.

Where as previously this would have been running like another action in line 2, it's now more or less running as a new event like it was on line 5.
To get around this you have to hit a top level event first. In this case you do something like:
